According to the National Wine Agency, grape harvesting in Georgia exceeded 231 thousand tons in 2018. Vineyards are not only growing in Kakheti and Racha-Lechkhumi regions but in almost every area of viticulture. In the process of primary grape harvesting and wine production, up to 25% waste is generated by solid parts of the grape bunches (bunch, skin, grape seed) and emptying, which are the best raw materials for making the curing-preventive powder, extracts, syrups, concentrates, pills, granules, alcohol, wine acid, grape seed oil, grape seed flour, nutriment paints, pectin, food fiber, tannin, granulated feed-stuff, the animal nutrition silage, fertilizers, etc. for the production of many other precious products. Therefore, it is more relevant to study the optimal technologies of recycling of secondary resources of thousands of tons of grape.
